Application November 23,' 1951, Serial No. 257,823

My invention appertains to slicing machines and more particularly to a portable machine or device for slicing and splitting buns for home and restaurant use. 1

Heretofore, when it was desired to slice buns, rolls, or the like for use in making hamburgers,

` barbecues, etc., it was customary to place an individual bun on the table, take a knife in one hand and while pressing down on the upper por- Y' tion of the bun with the other hand to cut the bun in a horizontal plane. Where it is necessary to slice alarge number of buns for immediate use or in readiness for a normal days need, the

, tediousness of the individual slicing operation as above set forth becomes clearly apparent.r For this reason, it is frequently found that the operator will attempt to hold two or more buns with one hand while endeavoring to slice them with a knife in the other, this being a practice which will not only produce inecient results in cutting, but often causes serious injuries to the hands of the operator.

It is, therefore, a primary object of my invention to provide a bun slicingfmachine which will eliminate the above disadvantages and which will slice the buns quicklyand eiciently in the desired l horizontal plane. v y

'Another vobject of my invention is toprovide a bunjslicing machine comprising a longitudinally vextending sheet metal casing having a walled central opening extending vertically `therethrough and adapted to receive and hold the bun or roll in a safe, out of the way, position'during the cut- Iting operation. l. Y .i v i l c A,furtherobjectof my invention is toprovide` the bun slicing machine ywith a sliding carriage mounted on the casing and carrying aslicing t knife which lis adapted, to travel in slots formed ,y in the wallsof the casing and .central opening to effectively slice the' bunsV held in the central opening. v f Still another object of this invention is to provide my bun slicing machine withr means associat- V,fed with the sliding,` carriage for permitting the `bun to drop to the surface under the machine J after it has been sliced. Y.

my" invention is a guide'l member and pusherplate, wherebyv when the sliding carriage is returned after the cutting operation to p ermit anew bun or roll to be placed f in the walled bun receiving opening;r the cut bun under the machine rwill be` conveyed out ofthe Way and infront of thejoperator. o, VAstill further object of my invention is to provide' a simple, practical and reliablefconstruc- 3 Claims. (Cl. 146-151) tion that is economical to manufacture, easy'to assemble and positive in its`operation.

With the above and other objects in view which will more readily appear as the naturetof the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

Apreferred and practical embodiment of the invention is shown-in the accompanying drawings, in which:

Extending vertically through the casing I is a centrally positioned walled opening I6 of a size and configuration to receive the hat roll or bun B. The side walls I'I, formed by the upper and lower portions I2, I3 of the casing II), are provided with longitudinally extending slots I8, and the cylindrical wall I9 of the central opening I6 is also provided with a slot 20 which sin alignment with and lies in the same horizontalplane as the slots: I8. Extending longitudinally on thetop wall `2I of the casing I0 is a pair of spaced guide beads 22 which are received in the guide grooves 22 of the sliding carriage II. Guide grooves 22' form .fafrsnpport or bearing surface upon which the carriage I I is adapted to travel.

Sliding carriage II is also cfms'tructef1in'two parts and lower portion 24 is rmly secured to the upper portion 23 by means of the bel'ts`25. -An inclined cutting knife 2.6 is secured between the uupper portion`2'3anidilowerportion 24 Othe'earriage Hyand during .the rsliding movement :of -thefcarriage H cuttingivknife '26 travelsin the v-zlong'itudinal vslots vIt and through "thefslot v2li 'of dzl'ie'centra'fl openingIS.

"ltheopposite edges .X28 and n2S of the sliding car- '-riageII 'in 'diagonalrspaced relation'whereby the knife is secured against lateral movement.

"The top plate'3`l! ofy the .sliding :carriage I I` has f'formed in its yforward end an arcuate cut-out I"portion i3 I "formed "therein to provide 'access .to

As

shown, when the bun B, illustrated in dotted lines of Figure 4, is placed in the central opening I6 and the sliding carriage II moved toward the left dotted line position, the knife 26 will cut the bun in half and the cut bun B' will drop in the direction of the arrows and be deposited on the table surface.

:Referringzinow to Figure 'ofthe rirawings, it can be seen that when'the carriage I I is returned to the right to permit a new roll or bun to be placed in the opening I6, the depending pusher A,platetmvill engage the out roll or bun B on the l5 table and hpush the same in the `direction of the I'arrows toward the dotted line position and guide .member 3J Iwhere-.=1',l;1e bun B will be conveyed in front of the operator.
